Read property from config server in spring boot 2.4

I have below implementation currently working in spring boot 2.3. But when I migrate the same to spring boot 2.4. properties not reading from config server.

Code

@ConditionalOnProperty({"app.xzy.hosts"})
public class clientConfig { 
 // implementation
}

bootstrap.yml

spring:
 cloud:
  config:
   uri: http://main-config-server.com
   username: user
   password: pass
   fail-fast: true

application.yml

app:
 xyz:
  hosts: ${app.main.config.hosts}

application.yml in config server

app:
 main:
  config
   hosts: http://myhost.com

This implementation is working fine in spring boot 2.3. But after the upgrade to spring boot 2.4 this giving below error in the startup.

Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'app.xzy.hosts' in value "${app.main.config.hosts}"

Finally figured out the issue.

bootstrap.yml file is no longer enabled by default. You need enable it by adding new dependency in spring cloud 2020.0.0 and it solved my issue.

   <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bootstrap</artifactId>
    </dependency>
